A method and system for creating a permanent and authentic history of a computer generated numerical digit enables one to track digit's life path. The method comprises embedding each digit with a tamper detectable date-time stamp including at least the date when the digit is generated in the computer. The system includes an encoder for providing the numerical digit with the date stamp, a storage for storing the encoded numerical digit, and a decoder for decoding the numerical digit to indicate at least the date of origin of the numerical digit.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system for creating a history of a computer generated numerical digit, comprising: a code generator, said code generator generating a time stamp representing a time when the numerical digit is generated; an encoder coupled to said code generator, said encoder encoding the numerical digit with the time stamp to generate an encoded digit; and a storage coupled to said encoder, said storage storing the encoded digit.
2. The system of claim 1 , further comprising a decoder coupled to said storage, said decoder decoding the encoded digit to reveal the history of the numerical digit.
3. The system of claim 1 , wherein said code generator is further configured to generate a second time stamp including a time when the numerical digit is changed.
4. The system of claim 1 , wherein said code generator is further configured to generate a second time stamp including a time when the numerical digit is terminated from the storage.
5. The system of claim 1 , wherein said code generator is programmed to generate the time stamp being tamper detectable.
6. A computer readable medium having an executable program stored thereon, the program comprising the steps of: in response to a computer generating a digit, generating a first code indicating a time of the computer generating the digit in accordance with a real time clock in the computer; encoding the digit by embedding the first code in the digit; and storing the digit in a storage.
7. The computer readable medium of claim 6 , the program further comprising the steps of: in response to the computer changing the digit, embedding a second code in the digit indicating a time of the computer changing the digit; and in response to the computer terminating the digit from the storage, embedding a third code in the digit indicating a time of the computer terminating the digit from the storage.
8. The computer readable medium of claim 6 , the program further comprising the step of decoding the digit to establish a history of the digit.
9. The computer readable medium of claim 6 , wherein the step of encoding the digit in the program includes embedding the first code in a bit plane of the digit.
10. The computer readable medium of claim 6 , wherein the step of encoding the digit in the program includes making the digit tamper detectable.
11. A method for creating a history of a computer generated numerical digit, comprising: generating a date stamp in response to the computer generated numerical digit; generating an encoded digit by embedding the computer generated numerical digit with the date stamp; and storing the encoded digit in a record medium.
12. The method of claim 11 , wherein generating a date stamp includes generating the date stamp representing date information of the computer generated numerical digit.
13. The method of claim 12 , wherein generating the date stamp further includes generating the date stamp indicating a date of origin of the computer generated numerical digit.
14. The method of claim 12 , wherein generating the date stamp further includes generating the date stamp indicating a date of a change of the computer generated numerical digit.
15. The method of claim 12 , wherein generating the date stamp further includes generating the date stamp indicating a date of the computer generated numerical digit being terminated from record medium.
16. The method of claim 11 , further comprising decoding the encoded digit to establish a history of the computer generated numerical digit.
17. The method of claim 11 , wherein generating an encoded digit includes making the encoded digit tamper detectable.
18. The method of claim 11 , wherein generating a date stamp includes generating the date stamp in accordance with a real time clock in a computer.
19. The method of claim 11 , wherein generating an encoded digit further includes by embedding the date stamp in a bit plane of the computer generated numerical digit.
20. The method of claim 11 , further comprising decoding the encoded digit to retrieve the date stamp.
